Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a cooling container for canned refreshing water or the like using a Peltier element.

[Background technology]

One example of what has been proposed in the past is a refrigerated box in which a pre-cooled cold insulator is placed inside an insulated box, and canned juice or the like is placed around it. In this type of product, the cold insulating material must be cooled in advance using an electric refrigerator or the like, and handling is complicated. In addition, there was a limit to the ability to keep the refrigerator cool when taking it with you for long periods of time, such as in a car.

On the other hand, there have conventionally been heat-retaining containers such as thermos flasks for drinking water, but these containers have heat insulation properties, and their cold-keeping ability is even worse than the above-mentioned refrigerated boxes.

[Purpose of the invention]

An object of the present invention is to provide a cooling container that can keep soft drinks such as juice cold for a long time and is suitable for carrying.

[Disclosure of the invention]

The cooling container of the present invention is characterized in that the container body has a Peltier element for cooling the stored object to be cooled, and the residual heat surface of the Peltier element is in close contact with the inner surface of the outer cylinder of the container body, which also serves as a heat sink. That is.

In other words, in this cooling container, the outer cylinder of the container body also serves as the heat sink of the Peltier element, so there is no need to provide space for a heat radiation fan or a forced cooling fan, making the whole compact and portable. A cooling container suitable for this purpose can be obtained.

Here, the Peltier element refers to a semiconductor element in which when a direct current is applied, one pole (surface) becomes high temperature and the other pole (surface) becomes low temperature due to the Peltier effect.

An embodiment of the present invention will be described based on FIGS. 1 to 4.

FIG. 1 is a longitudinal sectional view of the cooling container of this embodiment, FIG. 2 is a cross-sectional view thereof, FIG. 3 is a perspective view, and FIG. 4 is a perspective view with the lid opened.

As shown in the drawing, this cooling container 1 is composed of a cylindrical body divided into two vertically, one of which is a lid body 2,
The other side is the container body 3. The lid 2 is attached to one part of the container body 3 by a hinge 4 so as to be openable and closable, and is closed by engagement of a locking member 5 and a locking piece 6 on the other side. A storage chamber 7 for storing canned goods such as canned juice is formed inside. This storage chamber 7 is provided with a partition 8 on the bottom surface of the container body 3 so that two cans can be stored vertically side by side.

The container body 3 has an inner cylinder 9. It is composed of a cooling cylinder IO and a metal outer cylinder 11, and a cold storage material 12 is filled and sealed between the inner cylinder 9 and the cooling cylinder 10. The cooling cylinder 10 is made of a material with excellent thermal conductivity, such as aluminum. Also,
A heat insulating material 13 is filled between the cooling cylinder 10 and the outer cylinder 11 to prevent dissipation of cold heat, and a plurality of Peltier elements 14 are filled between the cooling cylinder 10 and the outer cylinder 11.
will be placed. Each Peltier element 14 is installed in the container body 3 at appropriate intervals with its cooling surface in close contact with the outer surface of the cooling tube 10 and its heat generating surface in close contact with the inner surface of the outer tube 11.

A male connector 15 for supplying direct current to each Peltier element 14 is attached to the end face of the container body 3, and the male connector 15 supplies direct current to the Peltier element 14,
The Peltier element 14 is activated. At this time, the cold heat generated on the cooling surface of the Peltier element 14 is sent to the cold storage material 12 through the cooling cylinder 10 and cools the object to be cooled housed in the inner cylinder 9. On the other hand, the heat generated on the heat generating surface of the Peltier element 14 is transferred to the outer cylinder 1.
1 Dissipated into the outside air from the outside surface. In order to enhance the heat dissipation effect on the outer surface of the outer cylinder 11, as shown in FIG. 3, the outer surface of the outer cylinder 11 is knurled to form uneven notches 6 to increase the surface area and increase the heat dissipation efficiency. .

The lid body 2 is composed of an inner cylinder 17 without a cooling cylinder and an outer cylinder 18, and a heat insulating material 13 is housed between them.

The standard method of using this cooling container 1 is to supply direct current to the Peltier element 14 as described above, and to cool the canned juice or the like stored in the storage chamber 7 with the cold heat generated by the Peltier element 14. When going out, the user removes the power cord and carries it with him, but if a car or bicycle battery is available, direct current is obtained from it to activate the Peltier element 14, thereby increasing the cold insulation effect. In addition, since the outer surface of the outer cylinder 11 is used as a heat dissipation surface, this cooling container may swing in the atmosphere or the cooling container 1
In order to maximize the cooling effect, it is preferable to use the device under conditions where the device is exposed to cold air, making it suitable for carrying along when hiking or cycling, for example.

〔Effect of the invention〕

Since there is no need to provide space for a heat dissipation fan or a forced air cooling fan, the entire system can be made compact, making it suitable for portability.
